RTC Battery for Raspberry Pi 5

The power management chip on the Raspberry Pi 5 is equipped with a real-time clock and a button cell charging circuit. This can supply the clock with energy when the primary power supply is off. The Panasonic ML-2020 Lithium Manganese Dioxide battery, equipped with a two-pin connection, is compatible with the battery connector on the Raspberry Pi 5 plate. The battery can be attached to the inside of a housing or other suitable location using a double-sided sticker.
